Security; to gain access to the system a User must first request to login to the system and then supply login credentials (user id, password). Once they are authenticated they must then successfully answer 1 of 5 random questions which user has already supplied answers for during the registration process. A user must register with the above information before they are allowed to login. For successful access, the system will provide a confirmation to the user. If unsuccessful an error message will be provided. The system allows three unsuccessful attempts before locking the account (for credentials and question). If the password is 60 days or older the system requires the user to change their password and then forces them to login again. Note: the user will receive a confirmation once their password has been changed successfully.

Given the narrative below, prepare a use case narrative. The event is initiated when the employee requests to checkout a piece of equipment. They are prompted for their Employee ID and the system confirms that the employee is authorized to check out equipment. If the employee is authorized, then for each requested piece of equipment, the system checks the equipment restrictions to confirm that the employee has been assigned an acceptable skill classification. If the request is for tracked equipment, the system can also check availability by making sure the equipment does not have an outstanding check-out. If the employee is authorized and the equipment available and not restricted from use by that employee, record the check-out. The system provides the employee with a receipt that details the check-out and the location of the equipment.
